## Summary description

Crossover VHF/UHF ZWR-400 from Telkom Telmor is a VHF/UHF signal combiner designed to merge or route VHF and UHF antenna signals. Suitable for use with broadcast TV reception systems, the unit enables combining separate VHF and UHF feeds into a single output for distribution to receivers or amplifiers. Typical applications include domestic and small commercial TV antenna installations.

## Long description

The Crossover VHF/UHF ZWR-400 by Telkom Telmor is a VHF/UHF signal combiner designed to merge or route separate VHF and UHF antenna signals into a single output. Intended for broadcast TV reception systems, this passive unit provides a straightforward method to combine two antenna feeds so they can be distributed to a single receiver, amplifier or coaxial distribution network. The device is aimed at domestic and small commercial installations where separate VHF and UHF antennas are used.
Advantages
The ZWR-400 offers a compact passive design that requires no external power and provides a simple physical interface for combining VHF and UHF feeds. Because it is passive, it introduces minimal electrical complexity and is suitable for use with existing antenna systems, splitters and amplifiers. The unit is manufactured by Telkom Telmor to standard mechanical and RF connection practices for easy integration into typical coaxial TV installations.
Suitable for
Combining a dedicated VHF antenna feed and a dedicated UHF antenna feed into one coaxial output
Domestic rooftop or attic TV antenna installations
Small commercial premises with a single distribution line to multiple receivers or an amplifier input
Situations where passive signal combining is required without introducing power or active electronics
When it may not be suitable
The ZWR-400 is a passive combiner and does not provide amplification, signal equalization or filtering beyond basic combining. If the installation requires active amplification, gain control, or selective filtering between VHF and UHF bands, a powered combiner or dedicated amplifier with band-specific processing may be more appropriate. Very long cable runs or environments with weak signals might need an active solution to maintain acceptable reception levels.
Key specifications
Function: passive VHF/UHF signal combiner
Inputs/Output: separate VHF and UHF inputs with single combined coaxial output
Intended application: broadcast terrestrial TV reception combining for domestic and small commercial systems
Power: passive, no external power required
Construction: compact enclosure suitable for indoor or sheltered outdoor mounting depending on installation practices
How to use
Install the ZWR-400 by connecting the dedicated VHF antenna coax to the VHF input and the dedicated UHF antenna coax to the UHF input, then connect the combined output to the receiver, distribution amplifier input or coaxial distribution line. Ensure connectors are tightened correctly and weatherproof any outdoor connections. If the rest of the system includes amplifiers or splitters, verify their compatibility and arrange the combiner so that any powered devices are located in accordance with manufacturer guidance to avoid backfeeding or signal loss.
What to consider before purchase
Whether a passive combiner meets your needs or an active amplifier/combiner is required for weak-signal locations
Compatibility of connector types and impedance with your existing antenna cables and equipment
Placement and environmental protection needed for outdoor or rooftop installations
System layout: position relative to antennas, amplifiers and splitters to avoid signal degradation
Usage recommendations
Use the ZWR-400 where separate VHF and UHF antennas provide adequate signal levels and a passive, no-power combining solution is preferred. For installations with marginal reception or long cable runs, pair the combiner with a suitable amplifier placed close to the antennas or consult a technician to determine optimal placement and additional filtering or gain requirements.
